Encode URLs to make them safe for use in web requests, or decode encoded URLs back to readable form — instantly, for free. Our URL Encoder & Decoder converts special characters like spaces, &, ?, #, and non-ASCII characters into percent-encoded format required by web standards.
URLs can only contain a limited set of ASCII characters. Spaces, special symbols, and non-English characters must be encoded (e.g., a space becomes %20) before being used in URLs. URL encoding is fundamental to web development, API integrations, link building, and working with query strings.
Why URL Encoding is Important
- API requests: Query parameters with special characters must be encoded to work correctly
- Link building: URLs containing spaces or special characters must be encoded for sharing
- Form data: Form submissions encode special characters automatically — this tool helps you verify
- Debugging: Decode encoded URLs to understand what parameters are being passed
